There’s a need for changes in wall design, detailing, and construction to move towards more highly insulated assemblies required to reach Net Zero and Net Zero Ready levels of performance. Exterior wall systems are an important consideration that determine much of the cost and constructability of a home. Details left for consideration on-site can lead to delays, costs, and deficiencies.

Natural Resources Canada (NRCan) is using learnings from its Local Energy Efficiency Partnerships (LEEP) Initiative in British Columbia to establish some common wall assembly designs and details that builders, designers, and trades across Canada can use or modify for Net Zero and Net Zero Ready Homes.
